Zygomycosis is an increasing threat to patients with human immunodeficiency virus (HIV) infection. Zygomycosis (formerly called mucormycosis) is the fungal infection with Mucor, Rhizopus, or other species that share a common morphology of large empty pauciseptate hyphae with rare random-angle branching and a collapsed "twisted ribbon" appearance. Morphology allows a specific diagnosis on frozen...

Abstract Bachground and objectives:Streptomyces is the most important genus in Actinomycetes family.The Streptomycetes are widely used in industry producing numerous chemical compounds including antibiotics, enzymes and anti- tumor agents. The aim of this study was to isolate soil-borne Streptomyces producing antimicrobial substances from soil of Golestan province of Iran and to survey anti-fun...
Black meristematic fungi are cosmopolitan and able to adapt to extreme fluctuations of ultraviolet radiation, temperature, and moisture and grow in exposed habitats such as stone surfaces. In a survey on fungi associated with fruit rots, leaf spots, canker, gummosis, dieback and trunk diseases of grapevine and walnut trees in Kurdistan Province (Iran), some black meristematic fungal isolates re...
During 2008, the presence of Paecilomyces species was studied in fields in Fars province. Soil samples were collected from 0–20 cm depth. The isolates were recovered using a soil dilution plate method directly from soil. Isolation was performed from soil using malt extract agar, rice agar, oat-meal agar and potato dextrose agar. Anamorphic characteristics such as morphology of conidiophores, ph...
abstract valerian medicinal plant (valeriana officinalis) is a perennial succulent plant that is natural lenitive and good ingrained of diazepam. this study was conducted in order to identify the fungal agents of rhizome and root rot of valerian. infected plant samples that showed the symptoms of rotting and necrosis were collected from karaj and used in order to isolate disease agents. symptom...
Nanocopper oxide (nanoCuO) is among the most widely used metal oxide nanoparticles which increases their chance of being released into freshwaters. Fungi are the major microbial decomposers of plant litter in streams. Fungal laccases are multicopper oxidase enzymes that are involved in the degradation of lignin and various xenobiotic compounds. We investigated the effects of nanoCuO (5 levels, ...
This review illuminates key findings in our understanding of grapevine xylem resistance to fungal vascular wilt diseases. Grapevine (Vitis spp.) vascular diseases such as esca, botryosphaeria dieback, and eutypa dieback, are caused by a set of taxonomically unrelated ascomycete fungi. Fungal colonization of the vascular system leads to a decline of the plant host because of a loss of the xylem ...
